How to Check the Result
Confirm the named interface state, objective change, resource movement, roster change, or physical outcome described above. If the current build displays a different rule, keep the official page's broad system description but treat the live prompt as the current operational instruction. Do not substitute an old screenshot or an unlabeled third-party value for the active build.
Common Problems
- Problem: Do not follow pre-June Conversion Field descriptions.
- Problem: Saving Matter without maintaining the route can end the run before the reserve matters.
- Problem: A high-mass enemy may improve the reward opportunity but also needs stronger displacement.

Win by pushing enemies off the route, not by reducing health. Start with one reliable displacement interaction, place and rotate towers during BUILD, observe a complete ATTACK wave, then add cards or upgrades that reinforce the same physical result.

Tower Lab replaces damage scaling with force, mass, size, stability, friction, and displacement. Grow, shrink, split, merge, push, pull, bounce, hook, fling, or redirect objects so enemies leave the route; heavier enemies need more effective knockback.
